ALARM TAXIMETER.

Application filed August 5, 1920. Serial No. 401,450.

To all whom it may concern:

Be it known that I, JUAN ALoNso GArro, a subject of the King of Spain. residing at Miranda de Ebro, in the Province of Burgos and Kingdom of Spain, have invented certain new and useful Improvements in Alarm Taximeters, of which the following is a specification.

This invention relates to an alarm taximeter which will. warn the driver of any vehicle propelled by motor traction of the necessity of close attention t his course, by means of a bell, klaxon or siren.

Simultaneously with the sound of the alarm, a. lamp lights the front part of the device, so that the driver can see the cause of the indication given.

When the vehicle passes through villages and towns, the alarm device will function automatically. For the purpose of describing the device, the standard distance of one kilometer has been adopted.

Referring to the drawings, in Fig. 1 (A) represents the change of alarm; (B) represents the adjustment of the working of the itinerary; (C) represents the change.

Fig. 1 is a front elevation Fig. 2 is a horizontal section Fig. 3 is a vertical section, and

Fig. 4 is a cross section.

The mechanism of the instrument to be described consists of first an adjustment of the numberof revolutions completed by the wheels of the vehicle in travelling one kilometer, to one revolution of the shaft (7) Figs. 2 and 3, and secondly an alarm device.

The reduction device consists of two parts,

an inner part inside the case of the apparatus and an outer part connected to this for the transmission of thenumber of revolutions completed by the wheels of the ve hicle to which the device is attached. This exterior part is not described here, as it depends upon the diameter of the wheels. The inner part is made up of a worm screw (1), Fig. 3 and 4:, at the extremity of which part (2) is attached the exterior part of the device. This worm screw engages with the helicoidal wheel (3), Figs. 2, 3 and 4:, placed upon the shaft (at) which supports the pinion (5) and transmits its rotation to pinion (6) fixed to the shaft (7 which completes the reduction. One complete revolution of the shaftis produced by the number of revolutions made by the wheels of the vehicle in covering one kilometer.-

The alarm mechanism includes a band or ribbon having thereon a fixed scale and a diagram of the route, together with circuit closing strips whereby the bell or siren is made to function.

The explanation of the itinerary band is as follows: Upon the vertical shafts (14) and (143) Figs. 2 and 3 are placed the coils (15) on which are wound the itinerary bands, and which wind on or off according to the direction in which the route is to be traversed.

I f after having traversed a given route it is desired to return over the same ground, the winding reel or spool begins to wind off, and the reel or spool which was unwinding commences to wind on.

The working of the apparatus is con trolled all the time by the shaft (11) Figs. 2, 3 and 1, which supports a roller 16 bound with rubber of a length equal to one kilometer to the scale of the diagram of the itinerary; the shaft (11) receives and transmits its rotation to the coils in the following manner: Upon the shaft (7) Fig. 4 is the double cog-wheel (17) Fig. 4. one half of.

which engages with gear (18) Figs. 3 and 4 situated at the lower end of the shaft (8). The upper end of this shaft 8 carries the cogwheel (9) Figs. 3 and t which engages with gear (10) therebytransmitting its rotation to the shaft- (11) Figs. 2, 3 and which holds the cog-wheel (12). The shafts (1 1) and (1 1) Figs. 2 and 3 carry at their ends a cogwheel and (13 respectively. Two horizontal shafts (19) Figs. 2 and 3 and Figs. 2 and 1 having at their ends the cog wheels (21) and transmit alternately the movement of the shaft (11) to (14) or (1%) according to the spool on to which the diagram ribbon panoramic band is being Wound.

This change is effected as follows:

First the shaft (7) Fig. 4 threaded at its ends is fitted with the head or button (53) for turning the shaft thereby to move the same in the direction of its axis to bring either the bevel gear wheel 17 or 17 into engagement with the gear 18 thus producing the change in the working of the mechanism. Second one end ofthe shafts (1.9) and (20) Fig. 2 carries the fixed wheels (23) the cogwheels (22) are loose on the shafts (19) and (20) with a small groove which fits into the wheels (23); these cogwheels engage with (13) and (13 Figs. 2 and 3 by the pressure tionthe rack (31) Fig. 3.

Fig. 2 situated inof the s viral 5 rin (25) 1 p b which fit over the side the metal caps (24) u cog wheels and through the centers of which pass the shafts (19) and (20). The length of these shafts, corresponding to the inside of the metal caps, and another length outside are threaded and upon them glide the cog-wheels (26) which carry a cylinder (27) which acting as a plunger upon the springs (25) brings the necessary pressure to bear to engage the cog wheels with (13) or (13) putting into motion the receiving coil.

The change of pressure is produced by the rotation of the knob (28) Fig. 2 fixedat the end of the shaft (29) Figs. 2 and 3 which carries the pinion (30) and puts into mo At the ends of this, on the front side is fixed an arm Figs. 2 and 3 the ends of which hold the racks (33) and (34) which engage with the cogwheels (26). By the rotation of the knob (28) Fig. 2 to right or left, the racks (31) (33) and (34) descend or ascend puttlng into rotation the cogwheels (26). The turn of the thread of these wheels with their shafts 19 and 20 are in contrary directions for which reason they alternately bring pressure upon the springs (25) Fig. 2 reversing the direction of rotation of the spools (15) leaving the unwinding spool absolutely free.

The rack (31) is situated inside a box (35) Figs. 2 and 3 fixed to a shaft (36) two pinions (37) engages with the rack situated at the bottom of the box, assuring a vertical movement. The shaft (36) Figs. 2 and 4 threaded at its extremity has a but ton head or finger engaging portion 39 whereby the manipulation of the shaft will cause it to move in the direction of its axis thereby causing the pinion 30 to engage or disengage the rack 31 which controls the racks 33 and 34 which engage with the cog wheels 26 whereby the said racks 33 and 34 may or may not act as brakes in the rotation' of the shafts (19) and (20). The main mechanism of the alarm reduces itself to the installation of a bell, klaxon or siren (54) Figs. 2 and 3 on the case of the device which works on a dry'battery, or accumulator (55) situated inside same: or by an acv cumulator attached to such vehicles as automobiles; when the device being described completes the circuit between the battery or accumulator and the siren or klaxon, the

latter omes into action.

The connection between the two parts is obt ined thus:

,Two vertical shafts (40) and (41) Figs.

2 and 3 support the armatures (42) and 7 strips of metal (44) in U shape as indicated,

(43) respectively. each one formed by two by the drawings. separated by a diaphragm of ebonite through the front part of these strip of metal gliding upon the armature (42) or (43) atached to the shafts (40) and (41) Figs. 2 and 3 completes the circuit and causes the bell, klaxon or siren to function.

The strong lines on the peep hole of the case Fig. 1 indicates the position of the vehicle on the route according to its direction with relation to the starting point of the route.

The contact breaker of the device acts upon the armature of shaft (40) or (41) according to whether the band is being moved from or to its starting point.

This change in the action is eli'ected as follows:

' The shaft (41) 3 carries two sectors (46) and (47) joined by a screw (49); the V shaft (40) carries the sector (48) joined with (47) by the lever (50). The sector (47) has at its end a small chain (79) which passing over the pulleys (70) is attached at the other end to the shaft (51). This shaft threaded at its extremity obtains by the rotation of the knob (52) Figs. 2 and 4 a movement of translation upon its bearing in the direction of its length this movement modifying the position of the armatures (42) and (43) Figs. 2 and '3 and also the contact break made by the diagram band according to the direction of the vehicle. The same contact breaker acts as switch for the lamp (71) Figs. 2 and 4 which lights up the front part of the device. The arrangement of the wires (71) Figs. 2 and 3 between the'battery or accumulator and the armature is shown on the drawings and are contained in a rubber tube (72). The spools destined to receive the itinerary diagram are dismountable in order to facilitate the rapid change of diagram.

The spools upon 'Which the band is wound consist of the disks 56and 58 shown in Figures 3 and 4 which are connected by the hollow sleeve 57 which may be fitted to the shaft 14 or 14 as the case may be by means of a bushing 73. i Y

In the upper discs (58) V are the gear wheels (59) Figs. 2, 3 and 4 which engage with the gears (60) fixed to the shafts (61) Figs. 2 and 3 suspended from the upper support (75) on which are supported the shafts (14) and (14*) Figs. 2 and 3. The shafts 61 having the operating handles'74 thereon may be rotated by the said handles to thereby turn the coils or reels to rectify the position of the band with. respect to the route. The direction of the itinerary between the coils is indicated by heavy lines on the drawings and determined by the shafts (62) Figs. 2 and 11. In the same manner as shaft (11) shaft (62) supports a rubber bound cylinder. The parts of the itinerary exposed to the View of the driver are included between the shafts (62) Fig. 3. The clamp springs (63) Figs. 3 and 4 fixed to the supports (77) are intended to keep the itinerary band in constant tension and to assist the action of the springs Finally, the taximeter is fitted with a distance meter, which is not described here as it is very generally known, it being deemed sufficient to state that it is worked from the shaft (7) Figs. 3 and 4 by cog wheel (17) Fig. 4 or by (64) which engages with (65) Figs. 3 and 4 putting into motion shaft (66) which carries the series of gear wheels (67) Fig. 3 and the signs 0 to 9. These wheelstransmit their motion to (68) situated on the shaft (69). The first six figures from leftto right constitute a pos sible total of 100000 kilometres and the last four by the rotation of the (80) Figs. 2 and 3 permit a return to zero at any moment.

References on the drawings indicate the following (76) supports upon which rest the various shafts mentioned (78) adjusting screws (7'7) means of securing solidity and a rigid whole. The whole mechanism is enclosed in a case as indicated by the draw ings.

What I claim is:

1. In a route indicator for vehicles, a flexible panoramic band having circuit closing members thereon, winding and unwinding spools for receiving and issuing the band, means for moving said band in accordance with the movement of the vehicle, and means for reversing the movement of the band, said means including a shaft having an exterior operating handle and a rack pinion on the inner end thereof, a rack device operated by said pinion and consisting of oppositely extending arm members having racks at their extremities, and electric terminal members arranged to be engaged by the circuit closing strips carried by the band.

2. In a route indicator of the class described, a panoramic band adapted to move forward or backward in the direction of its length,means for advancing the band in accordance with the distance travelled. by the vehicle, circuit closing strips carried by the band, electric terminal members arranged to be engaged by said circuit closing strips on the band, means for adjustablymounting said terminal members, a coupling connection therebetween, and means for effecting the adjustment of said terminal members including a shaft having an exterior operating connection and a flexible connection between the inner end of the shaft and one of said terminal members.

In testimony whereof he hereunto affixes his signature in the presence of two witnesses.
